Tips

To maximize performance, mount the charger in a well-ventilated area to aid passive cooling. Use the VictronConnect app to set the correct battery type and adjust charging parameters for your specific battery. When connecting multiple units in parallel, ensure all units have the same settings and use appropriately sized cables to handle the combined current. For remote on/off functionality, wire a switch or relay to the remote terminal to control charging without disconnecting the main power.
